Oregon's Brianne Theisen, who competes for Canada, fell to 14th overall after three events in the heptathlon with a shot put mark of 42 feet, 3 1/2 inches on Friday night at Olympic Stadium.

The 23-year-old Theisen, a seven-time NCAA champion for the Ducks, has a total of 2,816 points.

The new leader is Lithuania's Austra Skujyte with 3,126 points after a heptathlon world record in the shot put at 17.31m/56-9 1/2.

Great Britain's Jessica Ennis is second at 3,062 points, followed by Germany's Lilli Schwarzkopf at 2,947.

The top American is Hyleas Fountain in eighth at 2,884.

Theisen is just off her Day One PR pace of 3,803 points set at the 2012 NCAA Outdoor Track & Field Championships in Des Moines, Iowa, in June.

However, she ran 24.09 in the 200 at NCAAs, and given the fact that the Olympic Stadium track is rapidly building a reputation as a very fast track, she could match that score with a time of 23.93 or faster. Theisen established her PB of 23.90 at the Pac-12 Championships at Hayward Field in May.
